我有一个表，看起来像这样：的MySQL集团按行

Associate Pay_Code Hours Site Date  Week  Year 
Bill REG 8.0 US 3/3/2014 10  2014 
Bill REG 8.0 US 3/4/2014 10  2014 
Bill REG 8.0 US 3/5/2014 10  2014 
Bill REG 8.0 US 3/6/2014 10  2014 
Bill VTO 6.0 US 3/7/2014 10  2014 
Bill PERS 2.0 US 3/7/2014 10  2014

Mary REG 6.0 Canada 3/7/2014 10  2014 
Mary PERS 2.0 Canada 3/7/2014 10  2014 
Fred REG 8.0 England 3/3/2014 10  2014 
Fred REG 8.0 England 3/4/2014 10  2014 
Fred REG 8.0 England 3/5/2014 10  2014 
Fred REG 8.0 England 3/6/2014 10  2014 
Fred REG 8.0 England 3/7/2014 10  2014

Jethro REG 8.0 Africa 3/3/2014 10  2014 
Jethro REG 8.0 Africa 3/4/2014 10  2014 
Jethro REG 8.0 Africa 3/5/2014 10  2014 
Jethro REG 8.0 Africa 3/6/2014 10  2014 
Jethro REG 8.0 Africa 3/7/2014 10  2014 
Jethro OT 8.0 Africa 3/7/2014 10  2014 
Frank REG 8.0 Iraq 3/3/2014 10  2014 
Frank PERS 8.0 Iraq 3/4/2014 10  2014 
Frank PERS 8.0 Iraq 3/5/2014 10  2014 
Frank VACP 8.0 Iraq 3/6/2014 10  2014 
Frank VACP 8.0 Iraq 3/7/2014 10  2014

这个查询：

SELECT Pay_Code, Site, SUM(Hours), Week(Date,4), YEAR(Date) 

FROM table 

GROUP BY Pay_Code, Site, YEAR(Date), WEEK(Date,4)

给我：

Pay Code Site Sum of Hours  Week  Year 
OT   Africa 8.0    10  2014 
      Jamaica 5.0    10  2014 
PERS  Canada 2.0    10  2014 
      Iraq  16.0    10  2014 
      US  2.0    10  2014 
REG   Africa 40.0    10  2014 
      Canada 38.0    10  2014 
      England 40.0    10  2014 
      Iraq  8.0    10  2014 
      Jamaica 40.0    10  2014 
      US  32.0    10  2014 
VACP  Iraq  16.0    10  2014 
VTO   US  6.0    10  2014

什么我想要要做的是将Pay_Code组分组，以便进一步汇总。一些看起来是这样的：

Pay Code2   Pay Code Site Sum of Hours  Week  Year 
OT     OT   Africa 8.0    10  2014 
           Jamaica 5.0    10  2014 
Paid Shrink   PERS  Canada 2.0    10  2014 
           Iraq  16.0    10  2014 
           US  2.0    10  2014 
        VACP  Iraq  16.0    10  2014 
REG     REG   Africa 40.0    10  2014 
           Canada 38.0    10  2014 
           England 40.0    10  2014 
           Iraq  8.0    10  2014 
           Jamaica 40.0    10  2014 
           US  32.0    10  2014 
Unpaid Shrink  VTO    US  6.0    10  2014

的目标是通过网站来报告Pay_Code2场，按周，但Pay_Code2场在表中不存在。现在我查询大量的数据并使用数据透视表对我的行进行分组。如果可能的话，我想在MySQL中这样做。

什么是“付费收缩”，“REG REG”，“未付费收缩”？ – Taryn

为什么不添加一列“pay_code_2”或查找表？ – pce

@pce - 我有RO表，所以我不能添加任何字段。我不知道MySQL方法来设置组，即付费收缩= VACP + PERS，未付费收缩= VTO + LOA等。 –

听起来好像您正尝试基于PayCode值创建新类别。你可以尝试这样的事情：

SELECT CASE 
     WHEN Pay_Code = 'OT' THEN 'OT' 
     WHEN Pay_Code IN ('VACP','PERS') THEN 'Paid Shrink' 
     WHEN Pay_Code = 'REG' THEN 'REG' 
     WHEN Pay_Code IN ('VTO','LOA','BER') THEN 'Unpaid Shrink' 
     ELSE 'Unknown' 
     END as PayCode_2 
     ,YEAR(Date), WEEK(Date,4), SUM(Hours), Site, Pay_Code 
FROM table 
GROUP BY PayCode_2, Pay_Code, Site, YEAR(Date), WEEK(Date,4)
